Computer Geek slang. Originally started as the frase "Super Elite Hacker" but due to mispronunciation by Asian computer geeks, and the substitution of numbers for letters that they sort of look like, but not really, has devolved into its current form. Used to describe one who is unusaully dominant at a multiplayer video/computer game.
Chang totally thinks hes a 5UPER1337HACK50R, but he's really just a level 3 druid yuk yuk yuk.
